Output level:
The continuous recording time is for analog inputs
when the volume level is set to "VOL 0".
The continuous play time shows the value when the
volume level is set to "VOL 15".
The above values are the standard values when the
unit is charged and used at an ambient temperature of
77
°
F (25
°
C).
The operating time when using an alkaline battery
may be different, depending on the type and manufac-
turer of the battery, and on the operating temperature.
